IPC: B26D5/08
Filed: 1988-11-18
Abstract: PURPOSE:To eliminate the erroneous wiring of a drive coil by individually fixing the drive coil and a printed wiring board to a metal plate low in a coefficient of thermal expansion and connecting the terminal of the drive coil to the printed wiring board. CONSTITUTION:Coils 10 are wound around bobbins 9 and the lead-out wires 11 of the coils 10 are connected to the terminals fixed to the bobbins 9. Each of terminals 12 is bent at the central part in an elastically deformable state. Drive coils 8 are supported between mount plates 1 and plates 7 so as to correspond to the shaft part 4 of a drive shaft 3. When the drive shaft 3 falls to a predetermined position, the lower drive coil 8 is electrified.

IPC: G01B11/00
Filed: 1990-10-26
Abstract: PURPOSE:To prevent an image of a surface top from being focused, by selectively blocking reflected light from the surface of a lens excepting a surface part to be checked. CONSTITUTION:P-polarized light emitted from a semiconductor laser 1 is led through a collimator lens 13 and a 1/4 wavelength plate 15 so as to be turned into circular-polarized light which then reaches a stop 10 where the reflected light impinges upon a shield part 10a is blocked. The reflected light having passed through an opening 10b is then irradiated onto a surface part 4a of a lens 4 to be checked by way of a lens 13. Then, reflected light by the surface part 4a to be checked is led through a lens 3, the opening 10a of the stop 10 and the 1/4 wavelength plate 15 so as to be turned into S-polarized light which is then reflected by a polarized light beam splitter 14, and is focussed onto an optical position detecting element 8 by way of a converging lens 16 and an objective lent 17. Further, the positions of centers of gravity of an image of the point to which the reflected light is focussed by the element 18 in two directions (x, y) are turned into a voltages (x, y) that are then amplified so as to be indicated by a bright point on a display section 20. At this stage, the lens 14 is turned with respect to a holding frame 21, the bright point on the display section 20 is rotated to depict a circular locus. Thus, the radius of the circular locus is measured so as to know an eccentricity.
